Key Features

• Helps secure intermodal containers and RIG obstructions
• IP-68 flood-protected, chainless motor with fewer moving parts
• Industry-leading warranty options, up to 7-year parts / 5-year labor

Overview
Rite-Hite designed the SHR-5100 Shadow Hook® Restraint as an exclusive third‑generation rotating hook restraint engineered for the most demanding and most diverse loading dock environments. The Shadow Hook® technology provides increased wrap and reach to secure a wide variety of RIG-based trailers including intermodal containers and trailers with obstructed rear impact guards. Heavy-duty bearings, enhanced clad track and reinforced high-pressure points reduce downtime and unplanned maintenance while maximizing uptime.

Benefits

• Greater wrap and capture range to maintain engagement on the widest variety of RIG types (including outdated ICC bars, 4x4 RIGs and pentagonal RIGs)
• Reduces trailer separation accidents by securing trailers with rear-impact guard obstructions and intermodal containers
• Standard vehicle restraint status communication (red/green lights) to clearly show when safe to load/unload or depart
• Optional connected capabilities via a digital platform for real-time visibility, alerts and analytics (Rite-Hite ONE-enabled)

Safety at the Loading Dock
Proper RIG engagement paired with clear and constant restraint status communication helps prevent trailer creep, early departure, landing gear collapse and trailer pop-up. The SHR-5100 is interlock capable and integrates with loading dock controls and hazard-recognition systems to reinforce safe sequences of operation and reduce human error.

Designed and Installed for Productivity
SHR-5100 features aim to minimize downtime and maintenance while enabling efficient loading operations. The unit supports integration with automation and connected monitoring to track cycle counts, equipment trends and fault modes, enabling prioritized maintenance and reduced detention risk.

Product Specifications

• Exclusive Shadow Hook® Design
  • Third-generation machined steel hook with zinc dichromate finish
  • Spring-loaded, latch-free Shadow Hook cover provides more wrap for the widest variety of RIG-based trailers and creates a vertical barrier for obstructed RIGs
• Widest Working Range
  • Spring-loaded structural hardened steel housing automatically positions when a backing trailer contacts the unit
  • Engagement range extends from 9" to 30" above the ground; available carriage options (9" or 12")
  • Dual articulating nose extension on standard 9" carriages for widest coverage
• Reliable Performance
  • Dual clad track with ~50% more track strength for heavy loading environments and aggressive pull-out attempts
  • Full complement needle bearing carriage rollers and needle hook shaft bearings reinforce high-pressure points
  • Auto-refire technology restores safe engagement if the hook is challenged while in operation
  • Certified to meet and exceed ANSI MH30.3 performance testing standards
• Integrity of Installation
  • Enclosed 5/16" (8mm) welded steel housing designed and installed with (15) 5/8" wedge-style anchor bolts and 22" of weld to front curb angle to receive trailer impact
  • Completed dock survey required for each dock position to ensure safe and proper application
• Pull-Out Force Benchmarks
  • Installed with more than 100,000 lbs. of mounting force and 32,000 lbs. of pull-out force — roughly double what tractors can achieve in first gear
• Built for Harsh Environments
  • Military-grade corrosion resistant finish on rotating hook track, base plate and housing; endures 1,000 hours salt spray testing
  • Mounted above ground away from dirt, debris, snow, ice and standing water for durability and ease of maintenance
  • IP-68, flood-protected chainless motor provides high protection against dock flooding and removes maintenance-prone moving parts

Applications & Compatibility
The SHR-5100 is built to service the widest variety of trailer types, including standard over-the-road, pentagonal (5-sided), intermodal container chassis and trailers with obstructed RIGs. Reinforced components and heavy-duty bearings make it suitable for demanding industries such as food & beverage, pulp & paper and automotive. Standard NEMA 4X control panel supports powered (automatic) operation and integration with interlock controls and other dock-safety systems.

Warranty
Standard warranty: 5-year parts / 3-year labor. Extended warranty option: 7-year parts / 5-year labor.
